The Landshut War of Succession and the exile of Trithemius
The provinces of the Holy Roman Empire at the close of the Middle Ages did not represent natural administrative divisions: rather, they were created by continuous splits and mergers on the principle that every prince must have a territory to rule. When Georg, duke of Bavaria-Landshut, died without a male heir in 1503, his kinsman Albrecht, duke of Bavaria-Munich, saw his chance to unify the two domains under his rule, two centuries after they were divided between branches of the house of Wittelsbach. Georg, however, had planned otherwise, as had his ally Philip the Elector Palatine. Georg’s daughter Elisabeth was married to Philip’s son Rupprecht and their infant son Ottheinrich was the rival candidate for the succession.
Philip, the power behind his son and grandson, raised armies and formed a coalition of provinces. Albrecht did the same and, crucially, won the support of Maximilian I, who waived imperial claims in the matter as part of a political bargain. In a summer of warfare in 1504, Philip’s forces had some initial success, but the balance of forces was against him and, worse still, Rupprecht and Elisabeth both died of natural illness that year. Enemy forces raided the Palatinate and Philip sued for peace. A peace conference the following year granted the succession to Albrecht with the consolation prize of a small domain for little Ottheinrich to rule.
With the invasion of the Palatinate, Trithemius enters the story. Farms supplying his monastery were devastated and its sister monastery of Limburg was completely destroyed. Furthermore, Maximilian I had placed Philip and all his supporters, of whom Trithemius was one, under imperial ban, an act which deprived them of all legal rights and protection. During this period Trithemius moved his monastic library to a stronghold of Philip’s for safekeeping. In the spring of 1505, after the ceasefire but before the peace settlement, he went to confer with Philip about the sacked monastery. Events overtook him when hostile troops violated his own monastery in his absence: it is here, at the start of 18 months of exile, that the published correspondence begins.
